Linda that is so great! (Well, not great that the owners put them there...but great that you were contacted!)
I am so happy that you brought them home for a chance to feel loved again...bless your heart. I know how I would feel, given these circumstances...you have done everything right, there is no way you can know what people will do...you can put it in the contract, but once they are gone from your home, they are at the mercy of the new owners...I am just so happy that they found you!
Give those two beautiful babies a huge hug from me, will you?
